. 1 0 aZZ whom it may concern:

Be it known that YLQARTURVO VANNUCCI a subject of the Kingdom of Italy, residing at Belle Vernon, in the county of Fayette and State of Pennsylvania, have invented certain new and useful Improvements in Tin-Doubling Machines, of which the following is a specification. v

This invention relates to automatically operated means for folding or doubling metal sheets or packs, and is especially designed for the purpose of automatically dou' bling tin sheets or packs which are then-delivered to' the heating furnace. V

The main object of this inve'ntion is to provide durable and efficient automatically operated mechanism for doubling tin sheets after they are passed from the rolling mill, thereby dispensing With the'expensive manual labor heretofore generally employed in the performance of this doubling operation.

.A- further object of theinvention is-to so construct my improved and novel -mechanism as to accurately double the she etsand true up their opposite edges, at the same time avoiding the usual Waste of material which ordinarily occurs in the doubling operation, thereby reducing such Waste to a minimum. V 1

Another. object of the invention is to employ means for automaticallyifeeding the sheet to the'folding mechanism,so that said doubling operation. i V Further ob ects of, the nvention are to provide means for gaging, and regulating the amount of materialto' be sheared from boththe ragged androunded endportions 5 of the sheet; pincher org-ripping means for clamping eachside edge of the sheet curved platen for compressing the sheet in its doubled condition; means for operat ng ;sa1d pressing frame; means for turning the edges .of the folded sheetyhorizontally moyalole means for ejecting the sheet rearwardly;

.ineans for returning said movable means to its 'normalposition; shearing means, and -means for periodically throwing the cloubling mechanism out of operation, all of said line '14='14, Fig. 7 13, looking .of-the arrow.

Fig.,15, is a detail SBClZlQH QLkQHQOH the.

means and mechanism being Wholly automatic in their operation.

The foregoing and such other objects as Specification of Iietters Patent. 7 l 'atent djo fl 12,1920 7 may appear from the ensuing. description 1 are attained by the construction, arrangement, locatlon, combination and cooperation of the parts hereinafter more fully de scribed, illustrated in the accompanying .dravv1ngs,-.and particularly pointed out in 'the'claims appended hereto, it being understood that slight changes in the precise form,

proportions and minor details of the construction may be resorted to Without departm 'ing fromthe spirit or sacrificing any of the advantages of the invention.
